●
This section describes an example of user communication protocol settings for creating the following commands and
command operations.
• Transmission command for transmitting data using Constant (Hexadecimal), Registering Constant (Character),
Device Address, BCC, Constant (Hexadecimal) command settings when the trigger condition device address
changes to 1
• Receive command for receiving, processing, and storing data in device addresses, using Constant (Hexadecimal),
Registering Constant (Character), Skip, Device Address, BCC, Constant (Hexadecimal) command settings, for data
transmitted from an external device, when the trigger condition device address is 1

AB is selected.
Number of Registering Constants: 2
2
Write a value of 3132h to LDR210 and 3334h to LDR211 for Device Address for transmission command data.
3 Change the value of the trigger condition LM200 from 0 to 1 to send the command.

(05h)
• When data transmission is successfully completed, the Completed Device Address LM201 changes to 1.
• When the value of each bit of address number+0 for Status Device Address LDR220 is 0, transmission is completed
without an error.
